Abstract
A system for detecting memory corruption in an engine control module includes a variable selection module, an output module, an input module, and a response comparing module. The variable selection module selects a variable of a control system for testing. The output module outputs a predetermined value of said variable to a memory location where said variable is stored in said engine control module. The input module receives a response of said control system to said predetermined value when said predetermined value is written in said memory location. The response comparing module compares said response to a predetermined range and determines that said memory location is defective when said response is not within said predetermined range.
